Benefits of technology

The invention is a safety system that uses a Cause and Effect matrix to automatically generate control code and distribute it over safety controllers and applications. This system allows for testing and iteration of the safety system earlier in the development cycle and optimizes the allocation of control code. The Cause and Effect matrix can be used with various process industries and safety controllers. The invention also includes a tool for manipulating the Cause and Effect matrix and a computer program for generating control code and distributing it to safety controllers. The system includes a display for displaying safety data and a graphical user interface for accessing devices and signals in the safety system. The technical effects of the invention are improved safety, efficiency, and safety testing capabilities.

Problems solved by technology

This results in a complex combination of system and components.
This process takes time, it may have results that have not been predicted, and it presents opportunities for mistakes occurring in manual inputs and manual calculations.
A typical shutdown level will have a number of causes connected and will trip the effects connected to it.

Embodiment Construction

[0038]FIG. 1 shows elements of a graphical user interface of a cause and effect matrix in an industrial control system in a simplified diagram. Within an industrial control system the safety system is comprised in the control system and functions as an individual system in parallel with the control system, sometimes even enabling the same action, but with different decision chains.

[0039]A preferred embodiment of a user interface of the cause and effect editor tool comprises a cause and effect matrix (CEM). The cause and effect editor may be displayed on a suitable workstation display device and arranged with selection means for input etc. to a human machine interface (HMI). The cause and effect matrix has horizontal rows of causes and vertical columns of effects. The matrix includes a cause which is represented by a global variable and an effect which is represented by another, different global variable. Thus each cause input and each effect output are identified and represented in ...

Abstract

A method in an industrial safety system for controlling a process or equipment, which industrial safety system includes components with safety devices. The safety system enables signals to be generated as a result of an event or alarm, where the method includes creating an automated link between the event or alarm and an effect or an action to be taken upon receipt of the event or alarm signal due to the event. The method includes configuring one or more links between the event and the input, thus forming a cause and effect matrix, and also generating a control code using the cause and effect matrix for subsequent download of the control code to at least one process controller whereby a control signal is subsequently generated by at least one safety controller to initiate the action or effect.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a method in an industrial safety system for controlling a process or equipment, which industrial safety system comprises components with inputs and safety devices, that enables signals to be generated as a result of an event or alarm. It includes a method and devices for handling events in an industrial system, such as alarms, enabling an action according to an event in an industrial system, such as an alarm or other events, and includes forming a Cause and Effect matrix and generating code based on that matrix.BACKGROUND OF THE INVENTION[0002]An industrial process such as an installation for extraction or production of oil and gas products has a physical implementation comprising components such as devices and apparatuses for operation, control, regulation and protection of the process. The industrial process also comprises systems for functionality, control and supervision. This results in a complex combination of system...
